TIE FOR CHANNEL BARS Filed June 11. 1931 INVENTOR Z .190 la, BY

.A TTORNEY Patented Sept. 26, 1933 UNITED STATES PATENT OFFICE Claims.

This invention relates to novel improvements in ties for channel bars used in building construction. Present day fire-proof construction makes wide use of iron or steel channel bars which 5 serve as furring in walls or as reinforcements behind partitions, ceilings, or the like and as supports for metal lath. Such channel bars may be fastened directly to the walls or ceilings or may be suspended therefrom. In some instances one set of channel bars is supported in angular relationship and in contact with a second set of such bars, preferably of larger size. In construction of this type it is desirable to tie or fasten the channel bars to their supports or to suspend them in such manner that one flange of the channel bar shall be clear and free for further building operations.

One object of my invention is to provide a fastening for such channel bars which will leave '20 one flange of the channel bar clear for further building operations.

Another object of my invention is to provide a tie or fastening for a channel bar so arranged that the bar may be readily inserted in holding position on the tie and then locked against accidental removal.

A further object of my invention is to provide a tie of cheap material, economic in manufacture and adapted for use by unskilled labor to be used as an incident of placing the channel bar itself.

Other objects of my invention will appear from the following description of the preferred form as illustrated in the appended drawing in which:

Fig. 1 is a side elevation of a tie between two channel bars;

Fig. 2 is a vertical cross section taken on the line 2, 2 of Fig. 1;

Fig. 3 is a side elevation of a modified form; and

Fig. 4 is a vertical cross section on the line 4, 4 of Fig. 3.

By way of illustration I have shown in the drawing a channel bar 5 including upper flange 6 and lower flange '7. Such bars are found in building construction spaced parallel at varying distances and serving as furring or as supports for other building elements. In the drawing I have shown a second series of channel bars 8 which are usually approximately half the size of the channel bars 5. The channel bars 8 are extended at right angles to the channel bars 5 and the upper flange 9 of the channel bar 8 is in direct contact with the lower flange '7 of channel bar 5.

The channel bars 8 are held firmly against the adjacent flanges '7 of channel bars 5 by means of a tie 11. This tie has been shown to be made of flexible sheet metal although it may consist of other appropriate material.

One end 12 of the tie 11 has been folded or bent back on the tie 11 to form a hook which is suspended over the upper flange 6. This hook may be bent from the tie 11 manually when the tie is applied to the bar 5.

The opposite end of the tie 11 is bifurcated by means of a slit 13. The inner end of the slit 13 terminates in a transverse recess 14 which, in the example shown is substantially one-third the width of the tie 11. The slit 13 and the transverse recess 14 are proportioned to receive the web and flange 9 respectively of the channel bar 8. In this manner the portion 15 of the end of the tie may in a sense be termed a hook, bracket or support.

The remaining portion of this end of the tie 11 consists of a tongue 16 which is bent transversely of the tie along the line of the transverse recess 14 as indicated in Fig. 1. This looking tongue 16 is in a plane perpendicular to the tie 11 when installation is made. This is shown so in full lines in Figs. 1 and 2.

As soon as the channel bar 8 is positioned in the slit 13 and recess 14, the tongue 16 is bent downwardly into the dotted line position indicated in the drawing and forms a lock retaining the bar 8 with its upper flange 9 in close contact with the flange 7 of the other bar 5.

The use of this tie in the manner indicated provides a firm hold for the channel bar 8. At the same time it leaves the lower flange 10 of the bar entirely free for whatever the further building operations require in the way of a smooth surface without irregular projections.

In such instances as it may be desired to use a channel bar suspended in position I form the tie in the manner indicated in Figs. 3 and 4. The tie 17 is formed at its lower end in the manner above described having a slit 13 and a transverse recess 14 thus forming a hook like bracket or support 15. The flexible tongue 16 is also provided for retaining the bar 8 with its upper flange 9 in the recess 14.

The opposite end 18 of the tie 17 is cut in any convenient shape and provided with a hole 19. This hole receives a tie wire 20 which may be the customary one suspended from a roof, floor, slab or the like.

The tie 17 may be readily attached to the depending wire 20 in the desired position. The flange 14 of the bar 8 is inserted in the recess 14 either before or after the tie 17 has been installed and by means of the tongue 16 the channel bar 8 is then held in fixed position relative to the suspending element 20. Here again the opposite flange 10 of the bar 8 is entirely free of obstructions.

I have illustrated and described the preferred form of my invention solely for purposes of example and without intending to limit the invention other than to the terms of the following claims.

What I claim is:

1. A tie for a flanged bar said tie having fastening means at one end for attachment to a support and having the opposite end slit, said opposite end being recessed interiorly of the slit to form a bracket or support, and the remainder of the said end being flexible along the line of said recess to form a movable locking tongue.

2. A tie for a flanged bar said tie having fastening means at one end for attachment to a support and having the opposite end slit to form a supporting hook, the portion of the end adjacent the hook being spaced therefrom to closely form a hook for attachment to one of the bars,

the opposite end being slit into tWo portions spaced from each other slightly more than the thickness of the second bar and one of said portions having an inner transverse recess communicating with the slit opening, the other portion of the end opposite the slit opening being spaced to fit closely around the second bar and being flexible along the line of said'transverse recess.

4. A tie for flanged bars said tie comprising a member having one end bent back upon itself to form a hook for attachment around the flange of a bar for suspension therefrom, the opposite end of the member being slit into two portions spaced from each other slightly more than the thickness of the bar and one of said portions having an inner recess at right angles to the slit opening, the other portion of the end opposite the slit being flexible along the line of said transverse recess.

5. A tie for fastening together two intersecting flanged bars, said tie comprising a flexible sheet metal strip having one end adapted to be bent back upon itself to form a hook around the flange of one bar, the opposite end of the strip being slit longitudinally into two portions spaced to fit closely around the Web of the second bar, one of said strip portions having a transverse recess communicating with the slit and fitting closely around the flange of said second bar, and the other portion of strip opposite the slit being flexible along the line of the transverse recess.
